Safari using the reference implementation is meaningless because they don't even seem to turn on all features in it. Mozilla and Chromium declared that progressive decoding was the main blocker, the authors added it to libjxl-rs earlier this year, then now they're shipping it. Safari hasn't enabled progressive decoding or animation even though it's been in libjxl since 2022. If I wasn't in the trenches of Cordova/React development a decade ago, I would say I'm baffled.
